GRATE FOR COAL-STOVES.

Specification of Letters Patent No. 6,358, dated April 17, 1849.

To all whom it may concern Be it known that I, CALEB ISBISTER, of the city of Allegheny, county of Allegheny, and State of Pennsylvania, have made certain Improvements in the Construction of Coal- Stoves; and I do hereby declare that the following is a full and exact description, reference being had to the annexed drawings, making part of this specification, in which- Figure 1 is a vertical section of a stove showing the inside. Letter h isl'the fire grate having a plate a on the underside of it, in which is a notch 0 to retainthe bolt 8. This grate is shown by Fig. 2 and Fig. 3, in which the same letters show the same parts. t t are centers of motion. o v are fianches to hold the grate to its place. 6 is the ash drawer. 0 is a piece of metal made fast to the back of the ash drawer to work against the plate a; on the grate that the bolt .9 may be withdrawn and also to bring the grate again to its place after it has fallen into the drawer, as shown by Fig. P bounded by red lines. The drawer being moved forward the piece 0 on the back will strike the under edge of the plate a, and by continuing to move it forward it will raise the grate enough to let the bolt 8 be slipped under, and by continuing to move the drawer forward, or by pushing it back the grate will rest upon the bolt 8.

What I claim as my invention and desire to secure by Letters Patent is- The manner of lifting the grate to its place by means of the plate (1 attached to the underside of the grate combined with the piece 0 on the back of the drawer as herein described.
